NVIDIA has just launched another version of their GeForce Experience, incrementing the version to 2.1. This release allows video of up to "2500x1600", which I assume means 2560x1600, as well as better audio-video synchronization in Adobe Premiere. Also, because why stop going after FRAPS once you start, it also adds an in-game framerate indicator. It also adds push-to-talk for recording the microphone.
Another note: when GeForce Experience 2.0 launched, it introduced streaming of the user's desktop. This allowed recording of OpenGL and windowed-mode games by simply capturing an entire monitor. This mode was not capable of "Shadow Mode", which I believed was because they thought users didn't want a constant rolling video to be taken of their desktop in the event that they wanted to save a few minutes of it at some point. Turns out that I was wrong; the feature was coming and it arrived with GeForce Experience 2.1.
GeForce Experience 2.1 is now available at NVIDIA's website, unless it already popped up a notification for you.

NVIDIA has been upgrading their GeForce Experience just about once per month, on average. Most of their attention has been focused on ShadowPlay which is their video capture and streaming service for games based on DirectX. GeForce Experience 1.8.1 brought streaming to Twitch and the ability to overlay the user's webcam.
Until this version, users could choose between "Low", "Medium", and "High" quality stages. GeForce Experence 1.8.2 adds "Custom" which allows manual control over resolution, frame rate, and bit rate. NVIDIA wants to makes it clear: frame rate controls the number of images per second and bit rate controls the file size per second. Reducing the frame rate without adjusting the bit rate will result in a file of the same size (just with better quality per frame).
Also with this update, NVIDIA allows users to set a push-to-talk key. I expect this will be mostly useful for Twitch streaming in a crowded dorm or household. Only transmitting your voice when you have something to say prevents someone else from accidentally transmitting theirs globally and instantaneously.
GeForce Experience 1.8.2 is available for download at the GeForce website. Users with a Fermi-based GPU will no longer be pushed GeForce Experience (because it really does not do anything for those graphics cards). The latest version can always be manually downloaded, however.

Another update to GeForce Experience brings another anticipated ShadowPlay feature. The ability to stream live gameplay to Twitch, hardware accelerated by Kepler, was demoed at the NVIDIA event in Montreal from late October. They showed Batman Origins streaming at 1080p 60FPS without capping or affecting the in-game output settings.
GeForce Experience 1.8.1 finally brings that feature, in beta of course, to the general public. When set up, Alt + F8 will launch the Twitch stream and Alt + F6 will activate your webcam. Oh, by the way, one feature they kept from us (or at least me) is the ability to overlay your webcam atop your gameplay.
Nice touch NVIDIA.
Of course the upstream bandwidth requirements of video are quite high: 3.5Mbps on the top end, a more common 2Mbps happy medium, and a 0.75Mbps minimum. NVIDIA has been trying to ensure that your machine will not lag but there's nothing a GPU can do about your internet connection.
GeForce Experience 1.8.1 is available now at the GeForce website.

They grow up so fast these days...
GeForce Experience is NVIDIA's software package, often bundled with their driver updates, to optimize the experience of their customers. This could be adding interesting features, such as GPU-accelerated game video capture, or just recommending graphics settings for popular games.
Version 1.8 adds many desired features lacking from the previous version. I always found it weird that GeForce Experience would recommend one good baseline settings for games, and set them for you, but force you to then go into the game and tweak from there. It would be nice to see multiple presets but that is not what we get; instead, we are able to tweak the settings from within GeForce Experience. The baseline tries to provide a solid 40 FPS at the most difficult moments, computationally. You can then tune the familiar performance and quality slider from there.
You are also able to set resolutions up to 3840x2160 and select whether you would like to play in windowed (including "borderless") mode.
Also, with ShadowPlay, Windows 7 users will also be able to "shadow" the last 20 minutes like their Windows 8 neighbors. You will also be able to combine your microphone audio with the in-game audio should you select it. I can see the latter feature being very useful for shoutcasters. Apparently it allows capturing VoIP communication and not just your microphone itself.
Still no streaming to Twitch.tv, yet. It is still coming.
For now, you can download GeForce Experience from NVIDIA's GeForce website. If you want to read a little more detail about it, first, you can check out their (much longer) blog post.
ShadowPlay is NVIDIA's latest addition to their GeForce Experience platform. This feature allows their GPUs, starting with Kepler, to record game footage either locally or stream it online through Twitch.tv (in a later update). It requires Kepler GPUs because it is accelerated by that hardware. The goal is to constantly record game footage without any noticeable impact to performance; that way, the player can keep it running forever and have the opportunity to save moments after they happen.
Also, it is free.
I know that I have several gaming memories which come unannounced and leave undocumented. A solution like this is very exciting to me. Of course a feature on paper not the same as functional software in the real world. Thankfully, at least in my limited usage, ShadowPlay mostly lives up to its claims. I do not feel its impact on gaming performance. I am comfortable leaving it on at all times. There are issues, however, that I will get to soon.
This first impression is based on my main system running the 331.65 (Beta) GeForce drivers recommended for ShadowPlay.
- Intel Core i7-3770, 3.4 GHz
- NVIDIA GeForce GTX 670
- 16 GB DDR3 RAM
- Windows 7 Professional
- 1920 x 1080 @ 120Hz.
- 3 TB USB3.0 HDD (~50MB/s file clone).
The two games tested are Starcraft II: Heart of the Swarm and Battlefield 3.
